摘要
本文讨论了LnVO_4:Eu(Ln_(0.9)Eu_(0.1)VO_4,Ln=La^(3+)、Gd^(3+)、Y^(3+)、Sc'+和Lu_(3+))多晶粉末中Eu^(3+)离子~5D_0→~7F_2电偶跃迁(618.4nm)发光与化学组成、晶体结构和R—O键强之间的变化规律。
In this paper some results of the investigations on LnVO_4: Eu (Ln_(0.9)Eu_(?)VO_4, Ln: La, Gd, Lu, Y, Sc) crystal powders have been reported. The dependence of the relative intensities of the ~5D_0→~7F_2 (618.4nm) fluorescent transition of Eu^(3+) on the compositions, structure and R—O bond strength has been discussed in the LnVO_4: Eu.
